TRAINING

 Safety instructions are important! Read all

attachment and power unit manuals; follow all

safety rules and safety decal information. (Replace-

ment manuals and safety decals are available from

your dealer. To locate your nearest dealer, check

the Dealer Locator at www.WoodsEquipment.com,

or in the United States and Canada call 1-800-319-

6637.) Failure to follow instructions or safety rules

can result in serious injury or death.

 If you do not understand any part of this manual

and need assistance, see your dealer.

 Know your controls and how to stop engine and

attachment quickly in an emergency.

 Operators must be instructed in and be capable

of the safe operation of the equipment, its attach-

ments, and all controls. Do not allow anyone to

operate this equipment without proper instruc-

tions.

 Keep hands and body away from pressurized

lines. Use paper or cardboard, not hands or other

body parts to check for leaks. Wear safety goggles.

Hydraulic fluid under pressure can easily penetrate

skin and will cause serious injury or death.

 Make sure that all operating and service person-

nel know that if hydraulic fluid penetrates skin, it

must be surgically removed as soon as possible by

a doctor familiar with this form of injury or gan-

grene, serious injury, or death will result. CON-

TACT A PHYSICIAN IMMEDIATELY IF FLUID

ENTERS SKIN OR EYES. DO NOT DELAY.

 Never allow children or untrained persons to

operate equipment.

PREPARATION

 Check that all hardware is properly installed.

Always tighten to torque chart specifications

unless instructed otherwise in this manual.

 Do not connect a low-pressure hydraulic hose

into a high-pressure system—it will burst the hose.

Do not use a high-pressure hose in place of a low-

pressure hose—it is possible to rupture the valve.

 Always wear relatively tight and belted clothing

to avoid entanglement in moving parts. Wear

sturdy, rough-soled work shoes and protective

equipment for eyes, hair, hands, hearing, and head.

 Make sure attachment is properly secured,

adjusted, and in good operating condition.

 Power unit must be equipped with ROPS or

ROPS cab and seat belt. Keep seat belt securely

fastened. Falling off power unit can result in death

from being run over or crushed. Keep foldable

ROPS systems in “locked up” position at all times.

 A minimum 20% of tractor and equipment

weight must be on the tractor front wheels when

attachments are in transport position. Without this

weight, tractor could tip over, causing personal

injury or death. The weight may be attained with a

loader, front wheel weights, ballast in tires or front

tractor weights. Weigh the tractor and equipment.

Do not estimate.

 Make sure all safety decals are installed.

Replace if damaged. (See Safety Decals section for

location.)

 Make sure circuit selector lever does not hit

tractor cab, etc. throughout operating range of 3-

point hitch of tractor. Bend lever, if necessary, to

clear cab, but it should still be convenient to oper-

ate from the tractor seat.

OPERATION

 Do not allow bystanders in the area when oper-

ating, attaching, removing, assembling, or servic-

ing equipment.

 Do not operate equipment while under the influ-

ence of alcohol or drugs.

 Operate only in daylight or good artificial light.

 Keep hands, feet, hair, and clothing away from

equipment while engine is running. Stay clear of all

moving parts.

 Always comply with all state and local lighting

and marking requirements.

(Safety Rules continued on next page)

Safety is a primary concern in the design and

manufacture of our products. Unfortunately, our

efforts to provide safe equipment can be wiped

out by an operator’s single careless act.

In addition to the design and configuration of

equipment, hazard control and accident preven-

tion are dependent upon the awareness, concern,

judgement, and proper training of personnel

involved in the operation, transport, maintenance

and storage of equipment.

It has been said “The best safety device is an

informed, careful operator.” We ask you to be that

kind of operator.

OWNER SERVICE

 Keep hands and body away from pressurized

lines. Use paper or cardboard, not hands or other

body parts to check for leaks. Wear safety goggles.

Hydraulic fluid under pressure can easily penetrate

skin and will cause serious injury or death.

 Make sure that all operating and service person-

nel know that if hydraulic fluid penetrates skin, it

must be surgically removed as soon as possible by

a doctor familiar with this form of injury or gan-

grene, serious injury, or death will result. CON-

TACT A PHYSICIAN IMMEDIATELY IF FLUID

ENTERS SKIN OR EYES. DO NOT DELAY.

 Before working underneath, read manual

instructions, securely block up, and check stability.

Secure blocking prevents equipment from drop-

ping due to hydraulic leak down, hydraulic system

failure, or mechanical component failure.

 Never perform service or maintenance with

engine running.

 Before dismounting power unit or performing

any service or maintenance, follow these steps:

disengage power to equipment, lower the 3-point

hitch and all raised components to the ground,

operate valve levers to release any hydraulic pres-

sure, set parking brake, stop engine, remove key,

and unfasten seat belt.

 Keep all persons away from operator control

area while performing adjustments, service, or

maintenance.

 Always wear relatively tight and belted clothing

to avoid entanglement in moving parts. Wear

sturdy, rough-soled work shoes and protective

equipment for eyes, hair, hands, hearing, and head.

readable.

Periodically or Before Extended Storage

● Clean large debris such as clumps of dirt, grass,

crop residue, etc. from machine.

● Remove the remainder using a low-pressure water

spray.

1. Be careful when spraying near scratched or torn

safety decals or near edges of decals as water

spray can peel decal off surface.

2. Be careful when spraying near chipped or

scratched paint as water spray can lift paint.

3. If a pressure washer is used, follow the advice

of the pressure washer manufacturer.

● Inspect machine and replace worn or damaged

parts.

● Sand down scratches and the edges of areas of

missing paint and coat with Woods spray paint of
